Anyways, imagine getting changes that nobody wanted (i.e. nobody ever made such changes into a mod). That would be definitely worse. You should be impressed that they actually monitor and listen and implement "wanted" changes. Obviously as PieceofMind said, we will recognize some of these from mods.
To put it simply, I'd rather see changes that are inspired or outright ripped from mods than see no changes at all, or even changes that go against what every modder has been suggesting for the game. (EDIT oops, sort of cross posted with Bibor)
I agree with that, but I guess my negative feelings come from the fact that modders quickly and easily found these issues and created solutions to them shortly after the game was released....it just boggles my mind that professional game designers couldn't figure out stuff like this on their own before the release date.
Like I said, I think most of the changes are moves in the right direction and I am actually surprised that they've made such a drastic changes to their initial balance settings.
